How to Install a Motherboard

The third step of how to build a computer is installing your motherboard. The most important thing to remember while installing your motherboard is to be very careful with it. Make sure to not apply to much pressure on it and snap it.

Make sure to always hold it by the edges and before touching the motherboard make sure to touch a non-painted metal part on your computer case. This will ground you and discharge any built
up static electricity.

1. Lay your computer case onto its side, leaving the side that is open facing upwards. Begin to look where the holes are in your computer case and where they might line up with the holes in your motherboard. Your motherboard will have plenty of holes, so make sure it lines up with a decent amount of holes inside your computer case. Make sure to line up the holes at each corner of your motherboard to a hole on the computer case. Then try to line up as many holes in the middle of your motherboard with a hole on the computer case as well. These holes that line up will be the places we will install standoff screws on the computer case.

2. Once you have located which holes you will be using to screw in your motherboard, grab your standoff screws that came with your computer case and install the standoff screws into the case. Some motherboards also come with standoff screws and those work as well, use whichever you like. The standoff screws help hold the motherboard in place as well as provide a barrier between the motherboard and the computer case, as well as aiding in grounding static electricity.

Install the standoff screws into their correct holes inside the computer case.

3. Once you know which holes you will be using, and you installed your standoff screws into those holes, continue to lower the motherboard into place. Make sure all the rear connection points line up with their corresponding holes in the back of the computer case. After you make sure that it is lining up in the back, make sure the standoff screws that you just installed line up with the screw holes in the motherboard.

the external connectors line up with their holes.

4. At this point when everything is lined up, go ahead and grab the screws to screw the motherboard into the computer case. The screws should be decently long and the head of the screw should not be very wide. If the head of the screw goes over the grounding portion of the motherboard and is touching the motherboard in areas that is not designated for it, odds are you have the wrong screw. Begin to tighten all the screws into the motherboard. It is important to tighten the board enough so that it is firm and will not move, but make sure you don’t over tighten it to the point where the board has too much pressure and can crack.

5. Plug the 20+4 pin wire from the power supply into the motherboard. Look at your motherboard manual to determine where to put the power and reset switch wires from your computer case into your motherboard. Some computer cases also have a HDD light wire. All of these wires are very thin and have 2 pins associated with them on the motherboard. You can look at our image below to see what the 20+4 or 24 pin wire looks like (its number 2 in the image) that needs to be plugged into your motherboard

Once you’re certain everything is lined up and the motherboard is secure, we will move on to the next step on how to build a computer. The fourth step of how to build a computer is to install your Hard Drive and CD/DvD-ROM, click on the link below to continue.
